The aging and malfunctioning of cells that occurs when one part of the body is damaged can spread to other organs, a study has found. Scientists have shown for the first time that cell damage in a damaged liver can trigger a process associated with aging and dysfunction, and then spread to otherwise healthy organs […]
New High-Resolution 3D Maps Show How the Brain’s Blood Vessels Change With Age
Healthy blood vessels are not only important for heart health. Vascular well-being is critical for brain health and potentially for combating age-related cognitive decline and neurodegenerative diseases such as Alzheimer’s disease, according to a new study led by Penn State researchers. The findings point to a previously understudied but potentially crucial role that the brain’s […]
Sleep Apnea Can Impair Memory
Poor sleep quality can have a negative impact on memory. Research has already shown that fluctuations in nightly sleep duration and reduced sleep quality impair older adults’ ability to recall information about past events. It has been known for decades that important things happen during sleep in terms of consolidating memory and strengthening recollections. Current […]
Scientists Have Discovered that Ageing Clocks are Based on Random Events
Ageing clocks can measure the biological age of people with high precision. Biological age can be influenced by environmental factors such as smoking or diet and can therefore deviate from chronological age, which is calculated based on the date of birth. The accuracy of these aging clocks suggests that the aging process follows a program. […]
Can a High-Protein Diet Prolong Life?
Eating nutrient-rich foods can improve metabolic health and delay the ageing process. But what levels of macronutrients in the diet are appropriate to achieve this? To answer this question, Japanese researchers fed young and middle-aged male mice an isocaloric diet with varying levels of protein. They found that the mice were metabolically healthier when fed […]
